Go to ScienceCellular Life and GeneticsCell Structures
Play video, follow with Vocabulary slide
Have students write down definitions to vocabulary as they go through the powerpoint. Have students turn in vocabulary to their science teacher.

2. Biology Review
THE CELL

3. VOCABULARY Prokaryotic Lysosomes Eukaryotic Active transport
Nucleus Passive transport
DNA Diffusion
Mitochondria Osmosis
E.R. Cellular respiration
Ribosomes Photosynthesis
Cell membrane Concentration gradient
Cell wall Glucose
Chloroplast
ATP
Cytoplasm

4. CELL CLASSIFICATION There are two kinds of cells:
Prokaryotic cells- have no membrane around their nuclear material
Example- bacteria
Eukaryotic cells- have membrane-bound nucleus and many organelles
Example- plant and animal

5. Types of Cells Cells are the basic units of organisms.
Basic types of cells:
Eukaryotic
Prokaryotic
Bacterial Cell
Animal Cell
Plant Cell

6. Cellular Organelles and Functions
Nucleus- controls cellular activities
Golgi bodies- package proteins
Mitochondria- energy producer, site of cellular respiration
Endoplasmic Reticulum- highway out of the nucleus for cellular products
Rough- has ribosomes
Smooth- no ribosomes

7. Cellular organelles- continued
Vacuoles/vesicles-storage
Cell membrane- barrier
Cell wall- barrier in plant cell
Chloroplast-site of photosynthesis in plant cell
Ribosomes-site of protein synthesis
Lysosomes- waste management
Cytoplasm- “cell soup” where organelles sit

8. Cellular Transport There are two kinds of cellular transport-
1. Active transport-
Requires energy in the form of ATP
Used when: moving large molecules in or out of cell
Going against the concentration gradient
Needs: transport proteins in membrane

9. 2. Passive Transport Uses no energy
Diffusion: movement of particles from areas of high concentration to low concentration (With the concentration gradient)
Osmosis: movement of water with the concentration gradient
CO2 , O2 , H2O all cross cell membranes using passive transport

10. CONCENTRATION GRADIENT
Over time, molecules in areas of high concentration naturally flow to areas of low concentration until an equilibrium on both sides of the membrane is reached.

11. Diffusion in Lungs

12. Osmosis- “High to low is the natural flow”

13. ACTIVE TRANSPORT

15. Cellular Processes Photosynthesis- occurs in chloroplast of plant cell
Uses: carbon dioxide and water
Makes: glucose and oxygen
Cellular respiration- occurs in mitochondria
Uses: glucose and oxygen
Makes: carbon dioxide and water and ATP!!!

16. PHOTOSYNTHESIS

17. CELLULAR RESPIRATION

18. EQUATIONS for REACTIONS
Photosynthesis
6CO2 + 6H2O  C6H12O6 + 6O2
Cellular Respiration
6O2 + C6H12O6  6CO2 + 6H2O
What do these equations have in common?
